I have a leaking third brake light, and I found that the clip that provides the thread for the screw is missing. My issue is I have no idea how to identify the part number or even what the part is called. I've searched through the Chevy catalog and searched through Amazon, and the closest I can was "square clip plate nut," but that doesn't cross references with anything in the GMC catalog.

You can see in the below photos the right side has this clip that has a thread that the third brake light screws into, and you can see that the left one is broken and missing. That threaded clip is what I'm trying to identify the part number or what it is called.

Thank you

Is it leaking inside of the 3rd brake light housing, or is it just leaking into the interior from the gasket?

If just the gasket, here's one on amazon that I bought and it was a perfect fit: https://www.amazon.com/gp/product/B07H3RTDSW/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1

If you have water inside of the 3rd brake housing (inside of the plastic), look here: Leak at rear window -passenger side'ish

[edit]
Part number for the clip is 11546868
Pack of 15 on amazon for $16.70 https://www.amazon.com/au-ve-co-PRO...id=1674343328&sprefix=11546868,aps,651&sr=8-2

Probably should replace the broken brake light bulb while you’re there. I’m assuming you saw that already but just in case you hadn’t.
This is a huge reason why I change to LED's, but the funny thing is, I had an F150 that would disable cruise control because it thought a bulb was out due to the lower voltage. Solved with the regulator or whatever it was called, but seriously... ford.... that was your solution to letting a driver know a bulb was out? smdh. Too complicated to put a lightbulb indicator in the dash or something... just disable a feature and make you wonder how screwed your electronics are.

Housings like these melt very easily due to the heat on traditional bulbs then fuse around the bulb itself.

For a simple fix though, you can just get any old kind of foam sealer to keep the moisture out. Make sure it's not too thick and not too thin. Also a good time to clean out the housing. It's always satisfying putting something back together like this and making it all nice and new, or with LED's, better than new.
